Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k: m68k: Fix assembler constraint to prevent overeager gcc optimisation mac_esp: rename irq mac_scsi: dont enable mac_scsi irq before requesting it macfb: fix black and white modes m68k/irq: Remove obsolete IRQ_FLG_* definitions Fix up trivial conflict in arch/m68k/kernel/process_mm.c as per Geert.
